What I'm looking for

I seek a role that fosters collaboration, innovation, and continuous learning in network engineering.

I am a results-driven network engineer with over four years of experience supporting large enterprise and service provider environments. My expertise lies in deploying and maintaining secure, scalable infrastructure using technologies from Cisco, Juniper, and Sophos. I have a proven track record in SD-WAN, VPNs, BGP/OSPF routing, firewall management, and wireless network solutions. My passion for infrastructure resilience and collaborative delivery drives my commitment to continuous improvement.

In my current role as a Senior System Engineer at CWG, I successfully migrated over 1,000 users to Microsoft Teams Direct Connect and reduced Mean Time to Respond (MTTR) by 45% through automation scripts using Python and Bash. I also deployed and managed the Seceon aiXDR platform, enabling real-time threat detection across multi-tenant customer networks, which significantly improved incident response times.

Previously, I led a Juniper AI-Driven SD-WAN rollout for a Tier-1 Nigerian bank, deploying Sophos Firewalls for various clients, and automating configuration changes that saved over 30 engineer hours per month. My technical skills include network automation with Python, and I am certified in CCNP, JNCIS-Sec, Sophos, and AWS, which underscores my commitment to staying at the forefront of technology.
